President Clinton himself was the source of a controversial proposal to recruit at least 34 Democratic senators to declare that they would not vote to convict Clinton of any impeachment charges lodged by the House, according to congressional and administration sources. The account by these sources directly contradicts White House assertions that the proposal originated on Capitol Hill.The White House has attempted to distance the president from the proposal in recent days, after influential Sen. Robert Byrd, D-W.Va., strongly questioned the political and constitutional propriety of any such action. But congressional and administration sources have told Salon that it was Clinton himself who put forth the proposal in a conversation with Senate Democratic Leader Thomas Daschle, D-S.D., two weeks ago.
